1. Find z such that P(Z > z) = 0.12. 2. Find two values, equidistant from 0 on either side, such that the probability that a standard normal random variable will be between them is 0.40.

1. Find z such that P(Z > z) = 0.12.
P (Z>z) = 0.12
So p(Z z = 1.174987
2. Find two values, equidistant from 0 on either side, such that the probability that a standard normal
random variable will be between them is 0.40.
The two z values are ( -0.5244, 0.5244) ( from...
